1 of 12 EMERGENCY OVERVIEW RISK Causes burns. Risk of serious damage to eyes. Harmful by inhalation and if swallowed. Toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment. POTENTIAL HEALTH EFFECTS ACUTE HEALTH EFFECTS

SWALLOWED ! The material can produce chemical burns within the oral cavity and gastrointestinal tract following ingestion. ! Accidental ingestion of the material may be harmful; animal experiments indicate that ingestion of less than 150 gram may be fatal or may produce serious damage to the health of the individual. ! Ingestion of acidic corrosives may produce burns around and in the mouth. the throat and esophagus. <\p>. ! Antimony poisoning causes similar symptoms to arsenic poisoning although vomiting is more prominent. There may be changes in the rhythm of the heart beat. <\p>. EYE ! The material can produce chemical burns to the eye following direct contact. Vapors or mists may be extremely irritating. ! If applied to the eyes, this material causes severe eye damage. ! Direct eye contact with acid corrosives may produce pain, tears, sensitivity to light and burns. Mild burns of the epithelia generally recover rapidly and completely. <\p>. SKIN ! The material can produce chemical burns following direct contactwith the skin. ! Skin contact with acidic corrosives may result in pain and burns; these may be deep with distinct edges and may heal slowly with the formation of scar tissue. ! Skin contact is not thought to produce harmful health effects (as classified using animal models). Systemic harm, however, has been identified following exposure of animals by at least one other route and the material may still produce health damage following entry through wounds, lesions or abrasions. <\p>. ! Skin contact with antimony compounds may result in redness and severe irritation with the formation of itchy papules, pustules, skin lesions/ small septic blisters (antimony spots) within a few hours. Rhinitis may also result from dermal contact. ! Open cuts, abraded or irritated skin should not be exposed to this material. ! Entry into the blood-stream, through, for example, cuts, abrasions or lesions, may produce systemic injury with harmful effects. Examine the skin prior to the use of the material and ensure that any external damage is suitably protected. INHALED ! Inhalation of aerosols (mists, fumes), generated by the material during the course of normal handling, may be harmful. ! The material can cause respiratory irritation in some persons. The body's response to such irritation can cause further lung damage. ! Corrosive acids can cause irritation of the respiratory tract, with coughing, choking and mucous membrane damage. There may be dizziness, headache, nausea and weakness. <\p>. ! Inhalation hazard is increased at higher temperatures. ! (HCl) vapour or fumes present a hazard from a single acute exposure. Exposures of 1300 to 2000 ppm have been lethal to humans in a few minutes. Inhalation of HCl may cause choking, coughing, burning sensation and may cause ulceration of the nose, throat and larynx. Fluid on the lungs followed by generalised lung damage may follow. Breathing of HCl vapour may aggravate asthma and inflammatory or fibrotic pulmonary disease. High concentrations cause necrosis of the tracheal and bronchial epithelium, pulmonary oedema, atelectasis and emphysema and damage to the pulmonary blood vessels and liver. ! Inhalation of antimony can cause breathing difficulties and gastrointestinal upset including sore throat, shallow breathing, dizziness, weight loss, gum bleeds and anemia. Lung swelling and congestion can occur. <\p>. CHRONIC HEALTH EFFECTS ! Repeated or prolonged exposure to acids may result in the erosion of teeth, swelling and or ulceration of mouth lining. Irritation of airways to lung, with cough, and inflammation of lung tissue often occurs. <\p>. Long-term exposure to respiratory irritants may result in disease of the airways involving difficult breathing and related systemic problems. There has been some concern that this material can cause cancer or mutations but there is not enough data to make an assessment. Limited evidence suggests that repeated or long-term occupational exposure may produce cumulative health effects involving organs or biochemical systems.

Chronic minor exposure to hydrogen chloride (HCl) vapour or fume may cause discolouration or erosion of the teeth, bleeding of the nose and gums; and ulceration of the nasal mucous membranes. Repeated exposures of animals to concentrations of about 34 ppm HCl produced no immediate toxic effects. Workers exposed to suffered from gastritis and a number of cases of chronic bronchitis have also been reported. Repeated or prolonged exposure to dilute solutions of HCl may cause dermatitis. Repeated or prolonged exposure to antimony and its compounds may produce inflammation of the mouth cavity, dry throat, metallic taste, gum infection, perforation of the nasal septum and throat, laryngitis, headache, difficulty breathing, indigestion, nausea, vomiting, diarrhea, loss of appetite, anemia, weight loss, tightness and pain in the chest, sleeplessness, muscular pain and weakness, dizziness, pharyngitis,

2 of 12 bronchitis and pneumonia. Degenerative changes of the liver and kidney may occur. <\p>. Repeated exposure to low vapour concentrations can cause skin tenderness, bleeding of the nose and gums, chronic bronchitis, gastritis. Chronic exposure by inhalation may result in rhinitis, pharyngitis, tracheitis, and over a longer term, bronchitis and eventually pneumoconiosis with obstructive lung disease and emphysema.

8 of 12 STORAGE INCOMPATIBILITY " Inorganic acids are generally soluble in water with the release of hydrogen . The resulting solutions have pH's of less than 7.0. " Inorganic acids neutralize chemical bases (for example: amines and inorganic hydroxides) to form salts. Hydrogen chloride: " reacts strongly with strong oxidisers (releasing gas), acetic anhydride, caesium cyanotridecahydrodecaborate(2-), ethylidene difluoride, hexalithium disilicide, metal acetylide, sodium, silicon dioxide, tetraselenium tetranitride, and many organic materials " is incompatible with aliphatic amines, alkanolamines, alkylene oxides, aluminium, aluminium-titanium alloys, aromatic amines, amides, 2-aminoethanol, ammonia, ammonium hydroxide, calcium phosphide, chlorosulfonic acid, ethylenediamine, ethyleneimine, epichlorohydrin, isocyanates, metal acetylides, metal carbides, oleum, organic anhydrides, perchloric acid, 3-propiolactone, sulfuric acid, uranium phosphide, vinyl acetate, vinylidene fluoride " attacks most metals forming flammable hydrogen gas, and some plastics, rubbers and coatings. Reacts with mild steel, galvanized steel / zinc producing hydrogen gas which may form an explosive mixture with air. Segregate from alcohol, water. " NOTE: May develop pressure in containers; open carefully. Vent periodically. Avoid storage with metals, metal oxides, hydroxides, amines, carbonates, alkaline materials, acetic anhydride, cyanides, sulfides, sulphites, phosphides, acetylides, borides, carbides, silicides, vinyl acetate, formaldehyde and potassium permanganate.

Section 11 - TOXICOLOGICAL INFORMATION

ANTIMONY PENTACHLORIDE TOXICITY AND IRRITATION ! unless otherwise specified data extracted from RTECS - Register of Toxic Effects of Chemical Substances. TOXICITY IRRITATION Oral (rat) LD50: 1115 mg/kg Nil Reported Inhalation (rat) LC50: 720 mg/m#/2h Inhalation (mouse) LC50: 620 mg/kg Oral (guinea pig) LD50: 900 mg/kg ! Asthma-like symptoms may continue for months or even years after exposure to the material ceases. This may be due to a non-allergenic condition known as reactive airways dysfunction syndrome (RADS) which can occur following exposure to high levels of highly irritating compound. Key criteria for the diagnosis of RADS include the absence of preceding respiratory disease, in a non-atopic individual, with abrupt onset of persistent asthma-like symptoms within minutes to hours of a documented exposure to the irritant. A reversible airflow pattern, on spirometry, with the presence of moderate to severe bronchial hyperreactivity on methacholine challenge testing and the lack of minimal lymphocytic inflammation, without eosinophilia, have also been included in the criteria for diagnosis of RADS. RADS (or asthma) following an irritating inhalation is an infrequent disorder with rates related to the concentration of and duration of exposure to the irritating substance. Industrial bronchitis, on the other hand, is a disorder that occurs as result of exposure due to high concentrations of irritating substance (often particulate in nature) and is completely reversible after exposure ceases. The disorder is characterised by dyspnea, cough and mucus production. The material may produce moderate eye irritation leading to inflammation. Repeated or prolonged exposure to irritants may produce conjunctivitis. The material may produce respiratory tract irritation, and result in damage to the lung including reduced lung function. The material may cause skin irritation after prolonged or repeated exposure and may produce on contact skin redness, swelling, the production of vesicles, scaling and thickening of the skin.

Section 13 - DISPOSAL CONSIDERATIONS

US EPA Waste Number & Descriptions A. General Product Information Corrosivity characteristic: use EPA hazardous waste number D002 (waste code C) Disposal Instructions All waste must be handled in accordance with local, state and federal regulations. $ Puncture containers to prevent re-use and bury at an authorized landfill. Legislation addressing waste disposal requirements may differ by country, state and/ or territory. Each user must refer to laws operating in their area. In some areas, certain wastes must be tracked. A Hierarchy of Controls seems to be common - the user should investigate: " Reduction " Reuse " Recycling " Disposal (if all else fails) This material may be recycled if unused, or if it has not been contaminated so as to make it unsuitable for its intended use. If it has been contaminated, it may be possible to reclaim the product by filtration, distillation or some other means. Shelf life considerations should also be applied in making decisions of this type. Note that properties of a material may change in use, and recycling or reuse may not always be appropriate. DO NOT allow wash water from cleaning equipment to enter drains. Collect all wash water for treatment before disposal. For small quantities: " Dissolve the material (in water or acid solution as appropriate) or convert it to a water soluble state with appropriate oxidizing agent. " Precipitate as the sulfide, adjusting the pH to neutral to complete the precipitation. " Recycle wherever possible. " Consult manufacturer for recycling options or consult Waste Management Authority for disposal if no suitable treatment or disposal facility can be identified.
